Tank & Tankless Water Heaters
If you have an aging water heater, here are some signs it needs servicing, repair or replacement.
- If your hot water is not hot enough, you may need a new thermostat.
- If your hot water supply seems short-lived, then you may have sediment buildup in the tank that is taking the place of water that used to get heated.
- If you notice moisture around the bottom of your tank or rust spots, it is time to consider a new tank.
A Traditional water heater stores and preheats 30-50 gallons of water in a tank. That preheated water is used whenever a person showers, does the laundry or washes dishes. The tank then refills to be reheated once again.
When selecting a new water heater for your home, choose a water heating system that will not only provide enough hot water but also that will do so energy efficiently, saving you money.
The type of water heater you choose will also affect your water heating costs. One type of water heater may use a fuel type more efficiently than another type of water heater. For example, an electric heat pump water heater typically is more energy efficient than an electric conventional storage water heater. Also, an electric heat pump water heater might have lower energy costs because of its higher efficiency than a gas-fired conventional storage water heater, even though local natural gas costs might be lower than the electricity rates.
A Tankless water heater uses a heat source (electric or gas) to warm up cool water instantly on-demand whenever you need it rather than storing hot water in a tank.
Traditional hot water heaters typically live in your basement and provide gallons of hot water at one time: an 80-gallon tank heats enough water to shower, run a dishwasher, and do a load of laundry simultaneously. But standby energy loss is significant with traditional hot water heaters, and once you’ve exhausted the hot water supply, you’ll wait 20 to 60 minutes for the heater to cook up more.
A tankless water heater produces hot water only when you need it. When you turn on the faucet, water is heated on the spot as it flows through capillary-like pipes heated by either a powerful gas burner or electric coils.
While selecting to buy a tankless water heater you need to consider the following aspects:
- Anticipated requirement and water usage GPM (Gallons Per Minute)
- Readily available source of energy in your locality (natural gas/electricity)
- Size of tankless heater required
- Personal priority
- Installation cost
- Comparison between the cost of both type of heaters
- Location where you want to install the heater
